Ampeg Rocket Bass Combos

They are actually a couple pounds heavier than the Rumbles. I have the 500 and it weighs 36 lbs.; RB210 is 39. The 210 extension cab I have weighs 39 lbs, b/c it's got those big metal grabs handles on each side, combo only strap handle on top :thumbsup:
It was a bit of work to find the dimensions but here they are (along with the Thomann prices)

RB-108 / 167 Euros / 433 x 411 x 306 mm (1 mm = 0.0393700787 inches)
RB-110 / 273 Euros / 481 x 411 x 330 mm
RB-112 / 442 Euros / 543 x 462 x 360 mm
RB-115 / 609 Euros / 570 x 513 x 354 mm
RB-210 / 739 Euros / 654 x 513 x 354 mm

So, comparing the W and D of the RB115 and RB210 with the PF115HE and PF210HE:
W x D Portaflex = 533 x 363 vs Rocket Bass 513 x 354 means that the RB115/210 are an almost perfect fit on top of a PF115/210HE (as an extension cab)
Regarding height, with 598 mm, the PF115/210 is about 3 cm higher than the RB-115 and about 5,5 cm lower than the RB-210

So if your question is "Can I use the PF115HE or PF210HE as an extension cab for the RB-115 or RB-210?", my answer would be yes (based on the given data)
Came here to see these, as a person who had compared the Rumbles, BA's and Portaflexes in the past, prior finally decided that Ampeg is sound I'm after, and still a proud owner of the PF115HE and PF210HE cabs. Thanks for the weight comparison, BEADG63 and good job for conveying all of the dimensions, High Camp!!!
 
One thing I noticed is the RB110 doesn't have a volume level for AUX in like my BA110. That amp has been working more as a floor monitor than as an amp lately. It's actually a decent floor monitor.
Ya man, there were certain gigs I could pull off with just it as my house bass sound. It's not bad at all if you know its limitations.
 
For the RB-115, I'm assuming it's 200w when an extension cab is connected? Does anyone know what the wattage is with just the internal speaker? For example, the Rumble 200 is 140w by itself and 200w with an extension cab.
I would hope the full 200w with the cab alone. But who knows...the manual is not out yet.

With two cabs it looks like 100w for each cab based on the info from the Ampeg website:
Extension speaker output (8 ohms) = 100w

I wish all manufactures would publish power ratings at both 8 and 4 ohms. With the RB-210, you know you're getting gigging power without an extension. I myself like the RB-112 as all 100w go into the internal speaker.

It sounds like the RB-210 has the full 500 watts in the combo as it should be. I think its misleading for a company to advertise an amp as having say a '300 watt' power rating for instance and then in the fine print it says 'with an extension cab' you get the full output - fender hartke peevey they have all done that doesn't seem right to me . . . .

I was glad to see the front grill comes off; there is a tab in the lower right corner for pulling it off. Pretty important if you plan on recording one of these in a home studio. The picture is my Rumble 100 which shows where I put the Shure SM57 on a 12 inch speaker. If the front of the new Rockets weren't removable, that would have been a deal breaker for me. I think a Rocket would look pretty awesome sitting next to my Rumbles; not for comparison, but for versatility. Ampeg and Fender hang out together all the time in the real world, on stage and in the studio.

REALLY like the cosmetics of these combos.
Want to hear em'.
I thought the early B50 and B100 combos were the best combos Ampeg ever produced.

I just hope Yamaha/Ampeg isn't just loading an amp in to a PF cabinet.
The PF115HE cab I had, had to be rebuilt by me cause it rattled at all volume levels to a point it was useless on a live gig.

I maybe wrong, but from the way I'm understanding the write-up for the 210 on Ampeg's web-site it provides 250 watts to a external 8 ohm cabinet, so I'd say, it's 250 watts to it's internal drivers and 500 with a 8 ohm external cab plugged in.

Don't wrap yourself up into the "W" it doesn't matter as much as the efficiency of the cabinet.
I hope that Ampeg/Yamaha know to squeeze as much as they can out of the internal driver and not to rely on adding another to get the performance out. Otherwise they are going down the rabbit hole of confusion.
